Yes. This is expected behavior. The T2/A20 Boot ROM cannot boot directly from SATA. Its supported boot sources are SD/MMC, NAND, SPI NOR, and USB/FEL—SATA is absent. So you need a middle storage medium for the u-boot (SD/MMC, NAND, SPI NOR, and USB/FEL—SATA) between the main chip T2/A20 BROM and the SATA hard-disk.

Boards without 16MB SPI flash aka "-s16M" can't boot directly into the hard disk without the help of additional storage (either SD card or SPI flash). The U-Boot is too big to be stored on the EEPROM!

So options are - get "s16M" variant, or use SD card only for the U-Boot. USB/FEL—SATA doesn't appear like viable option since this requires another computer running sunxi-fel uploading the U-Boot on every cold boot.

A64 / Re: Use USB OTG in host mode

Last post by winfried - Today at 12:20:27 AM

Since also need this for my A64 Rev.E , to connect a keyboard on the mini USB-OTG, USB-A already used by another device:

You'd have to edit dts/dtb. Refer to the Olimage guide, there is info on how to change dts/dtb or kernel:

Installed the crosscompiler and can make dtb. So what I have to edit ?

found in arch/arm64/boot/dts/allwinner/sun50i-a64-olinuxino-1G.dts

Code Select Expand

&usb_otg {
        dr_mode = "otg";
        status = "okay";
};

I cannot figure out what to change, or what mode to define and where to find the documentation for this.

Any hint ?

A20 / Wich board to correctly move O...

Last post by oly - October 12, 2026, 02:24:18 PM

Hello,

Five years ago, I bought a LIME2 SERVER package (no more available) with

- 1 A20-OLinuXino-LIME2
- 1 metal box for it
- 1 metal case for SATA HDD
- 1 shield to connect HDD to OlinuXino, linking the box to the case
- 1 power supply


Nowdays, your product line offers many references for A20-OLinuXino-LIME2 with different options.
I've just bought a T2-OLinuXino-LIME2-IND and tryed to use your tool 'olinuxino-sd-to-sata'.
Doing so, I discover that without SPI flashmemory, I need to keep the SD card pluged inside the board so that the system can boot from HDD.
This is not what I want ...

Should I buy the T2-OLinuXino-LIME2-s16M-IND  version in order to use it only from    an SATA HDD (without SD card) ?

Hi all,

My Prophet server for the Neo6502 is online: https://prophet.3617.fr

It works with bocianu's prophet.neo client:

Code Select Expand

set server prophet.3617.fr
set port 8998
You can also browse the catalogue in a web browser and play most programs there. Wolfenstein 3D (beta) is available too.

Feedback welcome!

I got Debian 13 trixie on mine. The rootfs is on the SD card, and I forgot how I installed it. Probably I did upgrade from bookworm image to trixie at some point. I also have LVM + LUKS set up at boot.

Can you share where you purchased it?  I can't find it at Mouser or Digikey in the US.

Hello,

Thank you for your help.
I confirm it is the /etc/default/keyboard file (corrected in my initial post).

I'll try this ASAP and let you know.
